Thirty-eight patients (61 ureters) with primary vesicoureteral reflux who underwent extravesical antireflux surgery between Jan. 1975 and March 1989 were retrospectively analyzed. The overall postoperative vesicoureteral reflux (VUR) disappeared in 81.6% (31/38) of the patients, 86.9% (53/61) of the ureters. Among patients under 8 years old, VUR disappeared in all but one ureter. The postoperative VUR the disappeared in 95.7% (22/23) of the patients, 97.2% (35/36) of the ureters. Early postoperative early complications, including macrohematuria and bladder irritation were significantly fewer than those occurring in patients treated by the intravesical method. There were no serious late complications. Under restricted indications for patients under 8 years old, extravesical antireflux surgery might be clinically useful for treatment of VUR. Through the re-evaluation of length of submucosal tunnel, surgical outcome of this procedure might be improved.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
